Lgilg. Specification Application filed. June 28,

To all who/ni it may conce/m.'

2e it known that l., vi/Tiririmir d. dorms, a tes, residing at tisen or the United xoory, in the county of Gregory and otate i Dakota, have invented tain new il improvements in Resistance Appendages for Tractor-idlheels, of which the following is a specification.

This i ent-ion relates to a means for providino resistance for vehicle Wheels and moreI partie? larly for the Wheels of tractors, to prevent spinning of the Wheels While driving over muddy ground or upon ice or smooth surfaces. The invention includes ap pendages which may be readily secured to the tire and may be so adjusted that they will be disposed at a suitable distance from the outer side of a Wheel for the purpose mentioned, the construction requiring few and simple parte so that manufacture Will be practical, and of such form and arrangeinent that they may be applied to any tractor of ordinary type.

The invention consists of the novel construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanying drawing, wherein,-

Figure l is a plan vieiv of one of the angle-bars employed. Fig. 2 is a view in side elevation of a tractor wheel with the tire appendages mounted thereon. 3 is a transverse section through the Wheel, the view being a section on line 3?) looking to a second line lFig. d is an end view of one of the Wedge-shaped appendages employed.

y Referring now to the drawing for a more particular description, the invention is illus trated in connection with a tractor Wheel which may have any ordinary construction, its tire being indicated at 6.

ln order that the wheels of tractors er similar vehicles will bc prevented from sliding when driving upon soft ground or upon muddy surfaces l provide a plurality of groundeengaging appendages 7, these being maintained near the outer side of the Wheel, a plurality of angle-bars 8 being provided and disposed transversely of the tire to project outwardly thereof, one of the flanges t of each bar being provided with apertures as best shown in Fig. 1 and adapted to be secured to the tire by means of bolts 9.

Any suitable number of angle-bars and aptetters'atent. Patented July l2, id21.

pendages may be employed, these being disposed at uniform intervals of the tire. The ground-engaging appendages are each, preferably, of Wedge-shape, and as best shown in F ig. 4f, are provided with an L-shaped aperture b corresponding' to the form, in cross-section, of an angle-bar.

is thus described, the appendages may be readily mounted upon the angle-bars, said bars engaging in the apertures o', the parts being so proportioned that the `wealge-shaped appendages may have a slidable movement upon the bars, at the outer side of the wheel, and to be disposed at lesser or greater distances from the tire, as may be required, set-screws or bolts c being employel for securing the appendages to said angle-bars.

t Will be appreciated that, by use of the device as described, tractor-Wheels may be equipped at a very nominal expense with appendages which Will prevent spinning When driving over soft muddy ground, also that these appendages may be readily applied tothe tires or removed therefrom, as may be desired. Also it will be noted that the appendages 7, by means of the set-screws or bolts c may be adjusted longitudinally of the angleebars to be disposed at a predetermined distancev from the tire, this being of advantage to modify resistance, and when a greater degree of resistance is required, the distance between the appendages and tire 'may be increased. Also it will be seen that when the apertured flanges o', engage the periphery of tlie tire, the flanges l Will be disposed radially of the Wheel, as an additional aid to resistance. Also, the fact that the appendages 7 are of Wedge-shape, is considered to be an advantage, during operation, to permit mud to drop more readily from their convergent ends.

While l have described construction in detail, I do not Wish to be understood as limiting myself in this respect, and changes in form, size, proportion and minor details may be made, as found to be of advantage, said changes to be determined by the scope of the invention as claimed.

I claim, 1. ln ground-engaging appendages for the tires of tractor-Wheels, a plurality of bars adapted to be disposed transversely of the tire, a plurality of appendages slidably mounted on the bars, and set-screws or bolts engaging the appendages and also engaging vthe bars for maintaining tlie appendages at one of the sides at a predetermined distance fromv the tire.

2. ln groundengaging devices for the tires of vehicle Wheels, a plurality of bars disposed. transversely of the tire and projecting outwardly of the side oil the Wlieel, eacli bar having a flange adapted to lie upon tlie tire and having a flange disposed radially of the Wlieel, a plurality oi' apertured appendages eacli being disposed with its aperture receiving a bar, and meanst'o removably secure tlic appendages to said bar.

V3. In ground engaging devices for the tires of tractor-Wheels, a plurality of Wedgesliaped appendages eacli beingV provided with an aperture L-sliapcd in plan, a plurality of LarsA adapted to be disposed trans versely of tlie tire, ea'eli being adapted to be inserted Within and to approximately lill tlie aperture of an appendage, and set-screws or equivalent membersengaging tlie append- Ll. ln groundengaging` vdevices for the Y tires of vehicle Wlieels7 a plurality of angleiars mounted upon the tire and projecting outwardly of one of the sides of tlie Wheel,

'n each bar having one of its flanges engaging the tire and liaving laiigedisposed radially of tlie wiieel, a plurality of appendages approximately oi Wedgefsliape,V each liaving an aperture approximately of l -sliape Y yin plan and adapted to loe disposed with its aperture receiving an angle-bar7 and a plurality of setfscreivs .traversing tlieappend` ages for engaging said angle-bars.
